9mm ScrewCap with Septa Non-bonded Pre-slit Red & White – Globex

Globex – 9mm Blue ScrewCap with Septa Non-bonded Pre-slit Red & White PTFE Silicon (Pack of 100 Nos)

9 mm Blue ScrewCaps with Septa non-bonded pre-slit red & white PTFE/silicone septa are designed for secure and reliable sealing of ND9 screw-neck autosampler vials used in HPLC, UHPLC, and GC applications. The cap is manufactured from high-quality blue polypropylene to provide excellent chemical resistance, durability, and consistent torque during autosampler operation.

The septum consists of a PTFE (red) sample-contact layer laminated to a silicone (white) backing. The non-bonded design allows easy screwcap with septa replacement and flexibility for different analytical requirements. The pre-slit configuration reduces needle penetration force, minimizes septa coring, and ensures smooth autosampler injection while maintaining effective resealing and leak protection.

• 9mm screw thread vilas have a 9-425 GPI thread
• The closure is dimensionally equivalent to 11mm crimp cap vials.
• This means that they can be used in any autosampler that uses 11mm crimp cap vials.
• 9mm screwcaps with septa have an advantage over 11 mm crimp caps beacuse 9mm screwcaps with septa can easily be applied.

Key Features:

• Pre-slit screwcap with septa for easy needle penetration

• Reduced coring and particle generation

• Replaceable non-bonded septa

• Chemically inert PTFE contact surface

• Reliable resealing after multiple injections

• Leak-tight screwcap with septa closure

• Autosampler compatible

Applications:

HPLC / UHPLC, GC / Headspace GC, pharmaceutical analysis, environmental and food testing, chemical and research laboratories.
